Hello again,

I have observed that if I only have a few DNS servers defined in Unbound DNS: DNS over TLS, the response time is faster.
For example, when I have only defined 1.1.1.1 and 1.1.1.3, I get response times of around 50-60 ms.
Is it possible to have multiple DNS servers defined under Unbound DNS: DNS over TLS and still achieve fast response times?

I am experiencing issues with slow DNS response times (Unbound DNS + Adguard Home).

1. I have Adguard Home running in a container in Proxmox on its own VLAN xx.
2. In Adguard Home, I have defined Upstream DNS servers to 192.168.1.1:5353, and I have also defined Private reverse DNS servers to 192.168.1.1:5353.
3. In OPNsense, I have changed the Unbound DNS port to 5353.
4. In Services: Unbound DNS: DNS over TLS, I have defined: 1.1.1.1, 1.1.1.3, 149.112.112.112, and 9.9.9.9.
5. In System: Settings: General, I have set the DNS Server to the IP address of my AdGuard Home container.
6. Similarly, I have set the IP address of my AdGuard Home container under each interface in Services: ISC DHCPv4.

In Unbound statistics, I get:
Recursion time (average): 0.081140

In Adguard Home, I get an Average processing time of 82 ms.



Running OPNsense 24.1.7-amd64
AdGuard Home Version: v0.107.49


Do you have any suggestions on what I can do to reduce the response time?
